Online Play (Tom Clancy's HAWX)

Guys ... I wanted to play co-op with a friend ... the game was downloaded from a torrent, they wrote that a license, a crack was unnecessary, some kind of key is needed to play on the network ... maybe someone will give a program or a key in a personal message , my Internet is not high-speed, I will not play on an Internet for sure ... my friend and I would only be chopped on a LAN, help me?
